Fig. 2 — Differences of counts of cellular markers between PI-IBS and non PI-IBS. EC cells stained for PYY, CD8 positive lymphocytes, mast cells and CD68 positive macrophages were increased in PI-IBS patients, compared to non PI-IBS group. 5-HT positive EC cells showed increased tendency in PI-IBS group compared to non PI-IBS group. (p = 0.085 in DC, p = 0.058 in rectum). PI-IBS, postinfectious irritable bowel syndrome; PPY, peptide YY; IEL, intraepithelial. ^*p< 0.05. Cell counts/100 epithelial cells for 5-HT, IEL. Cell counts/160000 µm² for PYY, CD3, mast cell, CD68, calprotectin.
